Yes, this is true: current and *future* implementations of capscale/rda/cca (and future dbrda) will only have one data= argument. However, in addition to variables in the data frame given in data=, you can mix variables in the work environment in your formula. If you think you need to have several data frames for the data= argument, please consider cbind().
